TIGON Lock, interesting

[pradselost]

Hey all!
Haven't been around for a bit as my access is restricted at work now (shouldn't be on the first place at work but you know how that goes!) so it's nice to be back.
My wife found this lock at the swap meet here in Las Vegas and I thought I'd share. I can't find any information on it online, other than that it's made by a Chinese company. It's very odd...it has no spring pressure, and uses a disc system that looks like a cheap knockoff of an Abloy. The lock body itself is pretty sturdy.
Has anyone had any experience with these locks, or have any ideas for how to get started opening it?

[Safety0ff]

The disc mechanism looks similar to some of the cheap bike locks I've seen ($10 cad for 1, retail.) How to pick it is restricted to the advanced forum unfortunately.

[pradselost]

Eh, no kidding? I had figured it wouldn't be very advanced as a $4 lock, kind of a bummer.

It's actually more comparable to the "ABUS Plus" mechanism,
see e.g. viewtopic.php?t=13882

and these rotating disc tumbler locks are really harder to manipulate (even though they can be made and sold at low cost), and manipulation has always been restricted to the advanced section.

Cheers,

I actually have a VERY similar lock to this although it was listed as Fangyuan TOP SECURITY

I think they are all cheap abloy knock offs from china (and probably from the same manufacturer).

I tried a disk pick on it and it didnt just fall open so its not totally crap but im sure its probably one of the lowest quality rotating disc locks you can get:)

Does your disk lock pick have front or rear tension?

[JackNco]

that looks like its identical in construction to the "Jason" brand locks sold here in the UK? key is IDENTICAL apart from the branding. I believe they are rear tensioning Doug although I could be wrong.

Its a 9 disc mech if i remember. spot on for the price. I rate them over most cheap locks.

yes even I guess so its may be like Jason Brand

I got a set of 3 very, very similar locks, keyed differently, but master keyed some years ago off ebay. They are reasonably sturdy, but do have some non-stainless bits inside that rust over time in weather. Having said that, a squirt of oil every now and again has kept one of them functioning outside for ~5 years for me.

Mine, being masterkeyed weren't horribly resistant to manipulation compared to higher end rotating disk, but that's apparently a discussion for the advanced forum.

We have some members here from finland, where all the locks are abloy , I would defer to whatever they say about the ruggedness of this design, but it is my understanding that they don't have a lot of trouble with these, the design is over a hundred years on the market in its design, there are new keyway variations,

these locks have no springs, the discs and the separators between them would not even be wearing in normal operation, only if salt and grit got inside the keyway and did something to the sidebar would the lock fail.

well that and destructive attack

[Abus]

I think the difference between these knock offs and their ABUS/Abloy equivalents is mostly in cheap hardware, not so much in the cylinder, but the locking balls rust, etc.

[developper]

I just confirm that is a chinese lock

[Jaakko]

raimundo, you are correct on that Abloys and generally everything similar is reaully resistant to wear and weather. The sidebar in Abloy is the last to fail, as it is stainless steel and other parts are brass Generally the front door locks in a house last easily 25-50 years before they fail and in that time you have used one or two keys to their death

[raimundo]

I've never seen a worn abloy key, I suppose the wear comes from being on a keychain knocking around with other keys, I don't see the key wearing from use, theres just not the resistance or friction there.

Show us a picture Jaacko

[Abus]

I've seen a couple worn abloy keys, though I don't know their history.

Actually, the keys for my set of 3 chinese ABUS knockoffs, likely identical to the Tigon, are getting a bit worn. They're not a high quality as the abloy keys, in both manufacture and materials. I assumed that it was soft brass wearing against hard brass alloy disks with dirt, etc.
